Denmark's sports brand hummel is selling its popular "Tsumeta Inner" again this summer. Two types are available: the classic "Tsumeta Inner," which pursues a good feel against the skin, and the "Pitatto Tsumeta Inner," which balances high cooling value with a snug fit. You can choose the optimal piece according to your wearing scene and preference, especially during the summer season when performance tends to decline.

**"Tsumeta Inner" for Comfort During Exercise**

Hummel's Tsumeta Inner this year continues to use the popular fabric from last year. In addition to its contact cooling function, it boasts breathability, quick-drying properties, and skin detachment, quickly drying sweat during exercise and maintaining a comfortable feel. It is available as a sleeveless inner shirt in 4 colors, with junior items also offered.

Function ① Breathability: 1.4x

Adopting a thin mesh material, it achieves more than 1.4 times the breathability compared to our previous product (released in 2024). It prevents heat buildup and maintains coolness during exercise.

Function ② Quick Drying: 2x

The drying speed is approximately twice as fast, quickly drying sweat and dissipating body heat.

Function ③ Moisture Friction Resistance: 1/6th

The fabric's "skin detachment" property when wet (moisture friction resistance) has been improved to less than 1/6th of the previous level. Even when sweating, the fabric doesn't stick to the skin and maintains a smooth, detached feel.

【NEW】Stress-free Tagless Specification

To improve the comfort of the wear, the laundry care labels have been eliminated from this year and replaced with printed transfers. This reduces the stress of itchy tags against the skin, enhancing comfort.

**"Pitatto Tsumeta Inner" for an Instant Cooling Sensation**

If you want to experience coldness more directly, the Pitatto Tsumeta Inner is recommended. Its snug fit maximizes contact with the skin. It boasts hummel's highest contact cooling value and allows you to feel a cool sensation the moment you put it on. It is available in four items: shirts (sleeveless and long-sleeved) and tights (half and long).

Function ①: Zonal Mesh to Eliminate Stuffiness

Mesh fabric with good breathability is placed in areas prone to sweating, such as underarms and inseams. It effectively reduces the stuffiness during exercise and maintains a comfortable feel.

Function ②: Highest Level of UV Cut (UPF50+)

With a 99.9% UV cut rate and UPF50+, it provides peace of mind even on sunny days. Long-sleeved types and long tights are also available for sun protection. It supports outdoor sports and training.

This season, two types of Tsumeta Inner are released. The "Tsumeta Inner" caters to the need for a relaxed fit and is useful for club activities and daily wear. The "Pitatto Tsumeta Inner" is recommended for serious competitions, as innerwear during matches, and for outdoor sports where preventing performance decline due to sunburn is important. With a lineup that allows selection according to the usage scene, it comfortably supports summer sports.
